DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention

In the above-described known container, when the lid is peeled off the body, the film which forms the body deforms by the peeling force. Particularly in the case of the container formed of a thin sheet material such as film, the body irreversibly and plastically deforms by the peeling force. In this state, when the opening is covered again by the lid, the lid does not easily adhere tightly to the body. Therefore, if the lid does not adhere tightly to the body, the wet tissues stored within the body may get dry, or foreign material may enter the body. It is, accordingly, an object of the present invention to provide an improved technique relating to adhesion of a lid to a body in a container.

Means for Solving the Problem

In order to solve the above-described problem, according to a preferred aspect of the present invention, a container includes a body which is formed of a sheet member having an opening open to outside and has a storage space inside in communication with the opening, and a lid which covers the opening and can open and close the opening. The container is configured such that a storage article stored in the storage space can be taken out through the opening. The body extends along a first direction. The body has a holding part which is formed for holding the body in a region of one end of the body in the first direction. The lid has a fixed portion which is fixedly bonded to the body and a peelable portion which is formed contiguously to the fixed portion and can be peeled off the body. The peelable portion contiguously extends from the fixed portion toward the one end of the body in the first direction. The body has a reinforcing part which extends along a second direction transverse to the first direction at least between the opening and the holding part in the first direction and serves to reinforce the body.

According to this invention, by providing the reinforcing part extending along the second direction transverse to the first direction between the opening and the holding part, when the lid is peeled from the one end to the other in the first direction and the body is acted upon by a force which is generated at this time, the body having the reinforcing part can be prevented from being deformed. Specifically, the reinforcing part can prevent deformation of the body (the sheet member) which may be caused by peeling the lid. Particularly, by providing the reinforcing part upstream of the opening in the peeling direction, the reinforcing part can effectively prevent deformation of the opening and its surrounding region. As a result, adhesion between the lid and the body is improved when the opening is covered with the lid again after the lid is peeled.

According to a further aspect of the container of the present invention, the holding part is formed as a hanging part for hanging the body. The hanging part is preferably a through hole formed through the body, but it may be a hook provided on the body. Further, it is preferable for the hanging part to have such a strength that the hanging part is prevented from being destroyed when the body is hung and the peelable portion is peeled off the body. Specifically, the hanging part has a section modulus large enough to be prevented from being destroyed by the force which is generated when the peelable portion is peeled off the body, and by the force which acts upon the hanging part under the weight of the container having a storage article stored therein. The manner of “destroying” the holding part includes not only the manner of making the holding part unable to perform the function of holding the body, but the manner of irreversibly (plastically) deforming it.

In this aspect, by providing the hanging part as a holding part of the container, the container can be hung and used in that state. Therefore, a user does not have to hold the body when peeling the lid off the body. In other words, the user can peel the lid with one hand. Thus, the user's operation can be made simpler.

In this aspect, the hanging part is provided with a lateral seal part which is formed in the body.

According to a further aspect of the container of the present invention, the reinforcing part is provided in a region to be covered by the lid. The reinforcing part is preferably a reinforcing sheet formed separately from the body. In this case, the reinforcing sheet is fixedly bonded to the body. Further, the reinforcing sheet is preferably provided between the body and the lid.

In this aspect, by providing the reinforcing part in a region to be covered by the lid, particularly a region of the body off which the lid is peeled can be reinforced. Further, by providing the reinforcing part which is a reinforcing sheet formed separately off the body, the reinforcing part can be formed with a simple structure of simply attaching the reinforcing sheet to the body. In this case, the reinforcing part can be easily formed by attaching the reinforcing sheet to the body from outside.

According to a further aspect of the container of the present invention, the lid has a holding portion to be held by users. The holding portion is formed contiguously to the peelable portion on an end of the peelable portion facing away from the fixed portion in the first direction.

In this aspect, with the construction in which the lid is provided with the holding portion, the user can hold the holding portion and easily peel the lid off the body sheet. Thus, the user's operation can be made easier.

According to a further aspect of the container of the present invention, the fixed portion of the lid is fixedly bonded to the body.

In this aspect, with the construction in which the lid is provided with the fixed portion which is fixedly bonded to the body, the peelable portion can be left on the body in the peeled state. In other words, the lid can be prevented from being separated from the body when the peelable portion is peeled.

According to this invention, a container package is provided which includes a container and a storage article. The container includes a body which is formed of a sheet member having an opening open to outside and has a storage space inside in communication with the opening, and a lid which covers the opening and can open and close the opening. The storage article is stored in the storage space and can be taken out through the opening. The body extends along a first direction. The body has a holding part which is formed for holding the body in a region of one end of the body in the first direction. The lid has a fixed portion which is fixedly bonded to the body and a peelable portion which is formed contiguously to the fixed portion and can be peeled off the body. The peelable portion contiguously extends from the fixed portion toward the one end of the body in the first direction. The body has a reinforcing part which extends along a second direction transverse to the first direction at least between the opening and the holding part in the first direction and serves to reinforce the body.

According to this invention, by providing the reinforcing part extending in the second direction transverse to the first direction between the opening and the holding part, when the lid is peeled from the one end to the other in the first direction and the body is acted upon by a force which is generated by peeling the lid, the body having the reinforcing part can be prevented from being deformed. Specifically, the reinforcing part can prevent deformation of the body (the sheet member) which may be caused by peeling the lid. Particularly, by providing the reinforcing part upstream of the opening in the peeling direction, the reinforcing part can effectively prevent deformation of the opening and its surrounding region. As a result, adhesion between the lid and the body is improved when the opening is covered with the lid again after the lid is peeled.

According to a further aspect of the container package of the present invention, the holding part is formed as a hanging part for hanging the body. Further, when the body is hung and the reinforcing part is acted upon by tensile stress in the first direction under the weight of the storage article, the reinforcing part is provided and configured to prevent the opening from being irreversibly deformed by the tensile stress. Specifically, the thickness, rigidity and size of the reinforcing part are set such that the opening is prevented from being irreversibly (plastically) deformed even if the reinforcing part is acted upon not only by the tensile stress generated by peeling the lid, but by the tensile stress generated under the weight of the storage article when the body is hung.

According to a further aspect of the container package of the present invention, the storage article is an assembly of articles of the same kind. The articles are configured to be taken out through the opening one by one. The reinforcing part is acted upon by tensile stress in the first direction under the weight of all of the articles when the body is hung and any of the articles is not taken out yet. Further, the reinforcing part is acted upon by bending moment when the lid is peeled. The reinforcing part has a section modulus large enough to prevent the opening from being irreversibly deformed when the reinforcing part is acted upon by the tensile stress and the bending moment.

In this aspect, the opening can be prevented from being irreversibly (plastically) deformed by the weight of the storage article when the body is hung.

Effect of the Invention

According to this invention, an improved technique relating to adhesion of a lid to a body is provided in a container.

REPRESENTATIVE EMBODIMENT OF THE INVENTION

A container 100 for storing wet tissues 130 for dispensation is now explained as a representative embodiment of the present invention. Wet tissues 130 mean a sheet-type base material made of a fibrous material (cf. nonwoven fabric, gauze, cotton sheet, tissue paper) and impregnated with liquid (cf. alcohol, antiseptic solution, skin lotion). The wet tissues 130 are features that correspond to the “storage article” according to this invention. The container 100 containing the wet tissues 130 is a feature that corresponds to the “container package” according to this invention.

The construction of the container 100 of this embodiment is explained with reference to FIGS. 1 to 6. As shown in FIG. 1, the container 100 includes a body 110 and a lid 120. The body 110 and the lid 120 are features that correspond to the “body” and the “lid”, respectively, according to this invention.

As shown in FIG. 5, the body 110 of the container 100 is formed by an upper wall 110 a and a bottom wall 110 b and has a wet-tissue storage space 110H in which the wet tissues 130 are stored. Further, the body 110 of the container 100 has a through hole 112 formed in the upper wall 110 a. The wet-tissue storage space 110H is a feature that corresponds to the “storage space” according to this invention.

The wet tissues 130 are stored in the wet-tissue storage space 110H in such a manner as to be taken out one by one through an opening 112. Preferably, the wet tissues 130 are stored such that, when a first wet tissue 130 is taken out through the opening 112, an underlying second wet tissue 130 is partially exposed (pops up) outward through the opening 112. For example, the wet tissues 130 are individually folded in two and stacked one on another in such orientation that a folding direction of the wet tissues 130 is alternately reversed. At this time, an end of a lower half (in the laminated state) of a wet tissue 130 is located below an end of an upper half (in the laminated state) of the second wet tissue 130.

The body 110 of the container 100 is formed, for example, of a film which can be fusion bonded by heating or heat-sealed (which film is referred to as a “heat-sealing film”). In order to form the body 110 of the container 100, typically, the wet tissues 130 are wrapped with a heat-sealing film and then a longitudinal seal part (not shown) and lateral seal parts 111 a, 111 b in which the heat-sealing film edges are overlapped with each other are pressed and heated, so that the heat-sealing film edges are bonded at the longitudinal seal part and the lateral seal parts 111 a, 111 b. The longitudinal seal part is formed on the underside of the body 110 along the direction in which the heat-sealing film is fed during manufacturing of the container 100. The lateral seal parts 111 a, 111 b are formed on front and rear ends or opposite ends of the heat-sealing film in the direction in which the heat-sealing film is fed during manufacturing of the container 100, and extend along a direction perpendicular to the feed direction.

As shown in FIG. 2, the lateral seal part 111 a is wider than the lateral seal part 111 b in the long side direction of the body 110 (in the longitudinal direction in FIG. 2). A circular hang hole 114 is formed through the lateral seal part 111 a substantially in the middle of the lateral seal part 111 a. The long side direction of the body 110 is a feature that corresponds to the “first direction” according to this invention.

Various kinds of films which can be heat-sealed or fusion bonded by heating can be used as the heat-sealing film for forming the body 110 of the container 100. In this embodiment, in which the heat-sealing film is used for packing the wet tissues 130, the heat-sealing film is preferably of a type that can keep the wet tissues 130 in wet condition (or prevent them from drying). For example, a laminate film is used which includes a protective layer made of polyethylene terephthalate (PET) resin, a moisture keeping layer (drying prevention layer) made of aluminum, and a heat-sealing layer made of biaxial oriented polypropylene resin. In order to form the body 110 by using such a heat-sealing film, edges of the heat-sealing film are laid one on top of another such that portions of the heat-sealing layer (biaxial oriented polypropylene resin layer) are opposed to each other in the longitudinal and lateral seal parts. Thus, when the longitudinal and lateral seal parts are heated, the opposed portions of the heat-sealing layer (biaxial oriented polypropylene resin layer) are melted and bonded together in the seal parts. The protective layer may be omitted. Further, the moisture keeping layer (drying prevention layer) is not limited to an aluminum layer, but includes any layers which can keep the wet tissues 130 in wet condition (prevent the wet tissues 130 from drying) within the wet-tissue storage space 110H. The heat-sealing layer is not limited to a biaxial oriented polypropylene resin layer, but includes any layers which can be heat-sealed. The heat-sealing film is a feature that corresponds to the “sheet member” according to this invention.

As shown in FIG. 3, a reinforcing sheet 113 is bonded to the upper surface of the upper wall 110 a of the body 110 by an adhesive. As shown in FIGS. 4 and 5, a through hole 112 b is formed in a middle region of the reinforcing sheet 113. Specifically, the reinforcing sheet 113 is formed around the through hole 112 b. The through hole 112 b of the reinforcing sheet 113 and the through hole 112 a of the upper wall 110 a form the opening 112. Thus, the reinforcing sheet 113 extends along the short side direction of the body 110 perpendicularly to the long side direction between the opening 112 and the lateral seal part 111 a and the hang hole 114. The short side direction of the body 110 is a feature that corresponds to the “second direction” according to this invention.

As shown in FIG. 4, the reinforcing sheet 113 has a straight part 113 a formed on the side facing the lateral seal part 111 a and extending along the short side direction of the body 110. Specifically, the reinforcing sheet 113 is shorter than an opening-closing portion 120 b (see FIG. 2) of the lid 120 in the long side direction of the body 110. In this embodiment, the reinforcing sheet 113 is formed of the same material as the heat-sealing film for forming the body 110. The material of the reinforcing sheet 113 is not limited to this, but it may be formed of a more elastic material than the heat-sealing film of the body 110. Further, it is preferred that the reinforcing sheet 113 has a higher flexural rigidity than the heat-sealing film of the body 110. Although, in this embodiment, the reinforcing sheet 113 is bonded by an adhesive, it may be integrally formed on the upper surface of the heat-sealing film of the body 110 by heat sealing. The reinforcing sheet 113 is a feature that corresponds to the “reinforcing part” according to this invention.

The opening 112 can have various shapes which allow the wet tissues 130 to be taken out of the wet-tissue storage space 110H, such as an elliptical shape having major and minor axes, a circular shape and a rectangular shape. In this embodiment, the opening 112 has a circular shape. The opening 112 is a feature that corresponds to the “opening” according to this invention.

As shown in FIG. 2, the lid 120 includes the opening-closing portion 120 b, a base 120 a extending from the opening-closing portion 120 b toward the lateral seal part 111 b, and a tab portion 120 c extending from the opening-closing portion 120 b toward the lateral seal part 111 a (on the side facing away from the base 120 a). The opening-closing portion 120 b has a larger area than the opening 112. As shown in FIG. 5, the lid 120 is peelably bonded to the top of the reinforcing sheet 113 by an adhesive which is applied to one side of the lid. The tab portion 120 c protrudes from the straight portion 113 a of the reinforcing sheet 113 in the long side direction of the body 110. The adhesive can bond at least the opening-closing portion 120 b to the top of the reinforcing sheet 113 such that at least the opening-closing portion 120 b can be repeatedly peeled. For example, a pressure sensitive adhesive is used.

The base 120 a is fixedly bonded to a part of the top of the body 110 in which the opening 112 is not formed, and the opening-closing portion 120 b is bonded so as to cover the opening 112. The tab portion 120 c is used as a tab for opening and closing the opening-closing portion 120 b. Therefore, preferably, an adhesive is not applied to the tab portion 120 c. The base 120 a, the opening-closing portion 120 b and the tab portion 120 c are features that correspond to the “fixed portion”, the “peelable portion” and the “holding portion”, respectively, according to this invention.

In order to take out a wet tissue 130 from the wet-tissue storage space 110H, the user holds the tab portion 120 c of the lid 120 and peels the opening-closing portion 120 b off the top of the reinforcing sheet 113, so that the opening-closing portion 120 b is separated from the reinforcing sheet 113 and the opening 112 is opened. The opening-closing portion 120 b is normally bonded to the top of the reinforcing sheet 113 in order to prevent the wet tissues 130 from drying.

Operation of taking out the wet tissues 130 from the wet-tissue storage space 110H through the opening 112 is now described.

The lateral seal part 111 a is kept in a fixed position and the tab portion 120 c of the lid 120 is picked and pulled up by the user. Specifically, the tab portion 120 c is pulled in a direction of arrow A toward the lateral seal part 111 b. Thus, the opening-closing portion 120 b of the lid 120 is peeled off the reinforcing sheet 113, so that the opening 112 is exposed and the wet tissues 130 can be taken out through the exposed opening 112. In order to keep the lateral seal part 111 a in a fixed position, as shown in FIG. 6, the body 110 may be hung with a hanging string or rope 200 through the hang hole 114. By thus hanging the body 110, once the lid 120 is peeled in the direction of the arrow A, the lid 120 is held in that state under its own weight. The hang hole 114 is a feature that corresponds to the “holding part”, the “hanging part” and the “through hole” according to this invention.

The diameter of the hang hole 114 and the strength of the lateral seal part 111 a around the hang hole 114 are set such that the hang hole 114 is prevented from being destroyed when the lid 120 is peeled. Specifically, the diameter of the hang hole 114 and the section modulus of the lateral seal part 111 a are set such that the hang hole 114 is prevented from being destroyed by tensile stress which is generated on the heat-sealing film by separation of the adhesive when the lid 120 is peeled, and by tensile stress which is generated on the heat-sealing film under the own weight of the container 100. For example, in the case of the container package in which the weight of the container 100 is 5 g, the weight of the wet tissues 130 is 25 g, the diameter of the hang hole 114 is 5 mm, and the peel strength of the lid 120 is 250 g when the peeling speed is 100 mm/min, the film tear strength of the lateral seal part 111 a is set to be 280 g or higher.

Further, the reinforcing sheet 113 is configured such that the opening 112 is prevented from being irreversibly deformed not only by the tensile stress and the bending moment which act upon the heat-sealing film when the lid 120 is peeled, but by the tensile stress which is generated under the weight of the wet tissues 130 when the body 110 is hung. Specifically, when the tensile stress and the bending moment act upon the reinforcing sheet 113 at the same time, the side of the reinforcing sheet 113 acted upon by the tensile stress is more easily deformed plastically (deformed irreversibly). On the other hand, when the body 110 is not hung, the force acting under the weight of the wet tissues 130 is not directly involved in the deformation of the reinforcing sheet which may be caused by the bending moment when the lid 120 is peeled. Therefore, particularly, when the body 110 is hung in use, it is necessary to consider the elastic modulus and the section modulus of the reinforcing sheet 113 in order to prevent deformation of the reinforcing sheet 113 and the opening 112. The thickness and the elastic modulus of the reinforcing sheet 113 are set by considering the tensile stress which acts under the weight of the wet tissues 130. In this manner, deformation of the reinforcing sheet 113 and the opening 112 can be minimized so as to be prevented from affecting adhesion between the lid 120 and the reinforcing sheet 113. For example, the reinforcing sheet 113 and the lid 120 are formed of PET film, PVC film or the like, having the thickness of 50 μm or more and the thickness of 70 μm or more, respectively. Further, the body 110 is formed of film (e.g. PET12/AL6/CPP30) with the thickness of 48 μm.

In order to prevent the wet tissues 130 from drying, when the wet tissues 130 are not in use, the tab portion 120 c is returned back to the opening 112 side and the opening-closing portion 120 b is bonded to the top of the reinforcing sheet 113.

According to the above-described embodiment, by provision of the hang hole 114 in the body 110, the container 100 can be hung and held in that state. Thus, the lid 120 can be peeled off the body 110 with the container 100 held in the hanging state. Therefore, the user can peel the lid 120 with one hand, so that the user's operation of peeling the lid 120 is facilitated.

According to this embodiment, the lid 120 is peeled with the container 100 held in the hanging state, so that the lid 120 is held in the peeled state under its own weight. Therefore, the user can peel the lid 120 off the body 110 with one hand and then take out the wet tissues 130 through the opening with the same hand. Thus, the user can perform all these actions with one hand, so that the user's operation is facilitated.

According to this embodiment, the reinforcing sheet 113 is arranged on the top of the upper wall 110 a. Therefore, when the lid 120 is peeled from the lateral seal part 111 a side to the lateral seal part 111 b side, the heat sealing film for forming the body 110 can be prevented from being deformed. Specifically, by provision of the reinforcing sheet 113, the body 110 is reinforced around the through hole 112 a (the opening 112) having a lower rigidity. Thus, deformation of the body 110 can be prevented. As a result, adhesion between the lid 120 and the reinforcing sheet 113 can be improved when the lid 120 covers the opening 120 again, so that the wet tissues 130 can be prevented from drying,

According to this embodiment, by provision of the reinforcing sheet 113 arranged around the opening 112, particularly an area surrounding the opening 112 and having a low rigidity can be reinforced.

According to this embodiment, by provision of the reinforcing sheet 113 arranged on the top of the upper wall 110 a, the body 110 can be reinforced with a simple structure of simply adhering the reinforcing sheet 113 to the top of the upper wall 110 a after the body 110 is formed.

First Modification

A first modification to the reinforcing sheet 113 of the above-described embodiment is now described with reference to FIG. 7. In the first modification, a reinforcing sheet 213 is provided. In the other points, it has the same construction as the above-described embodiment.

The reinforcing sheet 213 is arranged only between the opening 112 of the body 110 and the lateral seal part 111 a. Specifically, the reinforcing sheet 213 extends along the short side direction of the body 110 between the opening 112 and the lateral seal part 111 a. The reinforcing sheet 213 has curved parts and straight parts 213 a, 213 b. The curved parts of the reinforcing sheet 213 have about the same shape as the curved parts of the lid 120 facing the lateral seal part 111 a in the long side direction of the body 110, and the straight parts 213 a, 213 b extend along the short side direction of the body 110. The reinforcing sheet 213 is longer than the opening 112 in the short side direction of the body 110.

The reinforcing sheet 213 is laid between the body 110 and the lid 120. Provision of the straight parts 213 a in the reinforcing sheet 213 makes it easier for users to pick up the tab portion 120 c formed at the end of the lid 120.

Second Modification

A second modification to the reinforcing sheet 113 of the above-described embodiment is now described with reference to FIG. 8. In the second modification, a reinforcing sheet 313 is provided. In the other points, it has the same construction as the above-described embodiment.

The reinforcing sheet 313 is arranged only between the opening 112 of the body 110 and the lateral seal part 111 a. Specifically, the reinforcing sheet 313 extends along the short side direction of the body 110 between the opening 112 and the lateral seal part 111 a. The reinforcing sheet 313 is rectangular and longer than the opening 112 in the short side direction of the body 110.

Like in the present embodiment, according to the above-described first and second modifications, by provision of the reinforcing sheet 213 or 313 which is arranged only between the opening 112 and the lateral seal part 111 a, deformation of the heat sealing film of the body 110 can be prevented when the lid 120 is peeled from the lateral seal part 111 a side to the lateral seal part 111 b side.

In the above-described embodiment and modifications, the hang hole 114 is provided as the hanging part in the lateral seal part 111 a of the body 110, but the hanging part is not limited to this. For example, in order to allow the body 110 to be hung, a hook may be provided on the body 110, or an adhesive tape may be provided on the lateral seal part 111 a of the body 110. Further, the container 100 is described as being used in the hanging state, but it is not limited to this. For example, the container 100 may be held by fixing the lateral seal part 111 a in a predetermined position such as on a desk or a shelf.

In the above-described embodiment and modifications, the lid 120 is formed by the base 120 a, the opening-closing portion 120 b and the tab portion 120 c, but it may be formed only by the base 120 a and the opening-closing portion 120 b. Further, in order to bond the base 120 a of the lid 120 to the top of the body 110, an adhesive having an adhesive strength to irremovably bond the base 120 to the top of the body 110 is used, but the adhesive may be of the type having an adhesive strength to peelably bond the base 120 a to the top of the body 110.

In the above-described embodiment and modifications, the reinforcing sheet 113, 213 or 313 is formed separately from the heat sealing film which forms the body 110, and provided on the top of the heat sealing film, but it may be provided on the storage space 110H side of the heat sealing film of the body 110. Further, it may comprise the reinforcing part which is integrally formed with the heat sealing film forming the body 110 by increasing the thickness of the heat sealing film of the body 110 between the opening 112 and the lateral seal part 111 a. The thickness of the heat sealing film is increased in part, so that this part of the heat sealing film is provided with higher rigidity and formed as the reinforcing part.

In the above-described embodiment and modifications, in order to make it easy for users to hold the tab portion 120 c of the lid 120, the straight part 113 a or 213 a is formed in the reinforcing sheet 113 or 213, but this purpose may be attained by other configurations. For example, instead of providing the straight part 113 a or 213 a, the tab portion 120 c of the lid 120 may be configured to protrude toward the lateral seal part 111 a.

In the above-described embodiment and modifications, the wet tissues 130 are folded in a pop-up manner and stored in the container 100, but the folding manner is not limited to this. For example, each of the wet tissues 130 may be folded in a so-called pocket fold in which the tissue is Z-folded and the edges of the Z-folded tissue are further folded to form a zigzag fold tissue and then the zigzag fold tissue is folded in the middle of the folds.
